Masterpiece gratings

McPherson's new masterpiece gratings that provide low stray light are now available. These concave corrected holographic gratings are specially manufactured for best performance in the Model 234/302 optical geometry. One of the new gratings expands the instrument range into the non-vacuum UV-Vis region. With new coating, the other enhances performance in the vacuum ultraviolet region 100 to 200nm. They allow new and legacy customers to implement the instrument over a greater wavelength range.
